Will mocking asks Huntsman if he would have believed climate scientists in the 70s on cooling-

Had Huntsman listened to the balance of the scientific evidence in the 1970s, he would be looking pretty good 30 plus years later. Contrast that with Will, who manages to still get what was said *then* wrong *today*, even with the benefit of hindsight!

“Never allow the public to cool off; never admit a fault or wrong; never concede that there may be some good in your enemy; never leave room for alternatives; never accept blame; people will believe a big lie sooner than a little one; and if you repeat it frequently enough people will sooner or later believe it.”

Re: The 1970s cooling mole … and yet, I can remember sitting in a university lecture hall in 1974 or ’75, listening to a senior professor reminding us that we were in an interglacial, and that there was no reason to assume that the ice sheets weren’t coming back. There was even a discussion of which climate would be tougher for us; Eocene tropical forests, or a few hundred meters of ice over Des Moines. As I recall, his view was that Des Moines would prefer the Eocene. Granted, this fellow was no climate specialist, and hell, he may have been the only academic in North America taken in by the popular meme. But BAMS historical reviews notwithstanding, the cooling idea certainly was out there …

[Yes indeed, it was out there. And various people have various recollections. But the issue (from my point of view at least) is what the science said at the time, and how scientists reported it -W]

It is true that (in the 70’s) there was a view among *geologists* (not so much among climate scientists) that our current interglacial would be similar in length to the previous interglacial, the Eemian.

The Eemian did last only about 11,000 to 14,000 years, and because we’re already about 12,000 years into the Holocene, it was considered possible or even likely that this could end any day. This view was amplified when it was found (in ice-cores) that the Eemian had had a quite sudden ending – it seemed as though it had receded suddenly into an ice age.

About fifteen years ago it became clear that the Holocene is MUCH more similar to the interglacial about 400,000 years ago – the orbital parameters are nearly identical. That interglacial did last WAY longer: at least 30,000 years.

In particular the eccentricity of the earth’s orbit is the same now as it was 400,000 years ago while the other parameters are changing very slowly as well.

The view from climate science was quite different from geology: changes in the radiative balance of the atmosphere are occuring way faster than any changes in orbital parameters.

To put it bluntly – climate science was right (the majority expected warming) while geology was wrong (ice age).
